Wait, there's more;
"Lindsay, despite appearances, is insecure and has relied on Samantha and their relationship to build her up," explains the pal. "Lindsay barely sleeps, which explains a lot of her behavior. She's exhausted. She can't even sit down for a minute without pacing around the room. It's really sad."

Looks like Lindsay's really having a tough time forgeting this one.

Despite all of these chaos, there's still good:
"Lindsay never realized until this happened how important her sister was to her," the friend says.

"Through all of this, her sister(Ali) has been there for her and coaching her through it. Lindsay doesn't even know what she would have done without her."
